Regulators equipped with anti-flooding hood

SS/BE/20140209 - Version 1We have conceived an anti-flood system, covering a surface of 10600 mm2, to be fitted to the whole range of the regulators designed for residential applications, buried version (regulator with capacity equal to or below 50m3/h). The “anti-flooding hood” system described above is therefore adaptable to all our models for series S1, S3 and S4 .Thanks to this system, the gas-regulator can be easily reset or put into service and the connections can be disassembled without any need of system dismantling. An identification plate, identical to that of the regulator, can be positioned into the anti-flo-oding hood. Some materials composing the regulator and in contact with the surrounding atmosphere shall be submitted to surface treatment in order to increase the product longevity in a very humid environment or subject to flood.The parts in contact with the atmosphere made of: - Zamak will be covered with an electrolytic protective layer (dichromated zinc coating 18µ); - Aluminium shall undergo a chemical reaction (anodizing). The springs in contact with the atmosphere must be in stainless steel. (resetting lever, first and second stage pressure regulating spring).The designs of these regulators foresee that all vents will be protected by this system.
